But a few years ago, it was discovered that former OED editor Robert Burchfield had inexplicably struck thousands of words from the record, most of them Americanisms. Lexicographer and OED editor emeritus Sarah Ogilvie talks with Bob about Burchfield and her new book, Words of the World: A Global History of the Oxford English Dictionary.
